Abstract
Methods and apparatus, including computer program products, for a fast hop frequency hopping protocol. A method includes transmitting from a radio frequency identification (RFID) interrogator a continuous wave un-modulated radio frequency (RF) signal conforming to a fast hop frequency hopping protocol in which each hop of a plurality of hops spans at least one bit but less than the totality of bits to be sent from a single RFID device data in a single communications session.
Claims18
A method comprising:
- transmitting from a radio frequency identification (RFID) interrogator a continuous wave un-modulated radio frequency (RF) signal conforming to a fast hop frequency hopping protocol in which each hop of a plurality of hops spans at least one bit but less than the totality of bits to be sent from a single RFID device data in a single communications session.
A method comprising:
- in a radio frequency identification (RFID) interrogator, transmitting a command using a communication protocol to a RFID device;
- and
- receiving a response from the RFID device conforming to a fast hop frequency hopping protocol.
A radio frequency identification (RFID) interrogator comprising:
- an integrated circuit, the integrated circuit coupled to a radio frequency (RF) transmitter through a digital-to-analog converter (DAC), the RF transmitter transmitting a continuous wave un-modulated radio frequency RF signal conforming to a fast hop frequency hopping protocol in which each hop of a plurality of hops at least spans one bit but less than the totality of bits to be sent from a single RFID device data in a single communication session.
A radio frequency identification (RFID) device comprising:
- an antenna linked to a transmit/receiving circuit, the transmit/receiving circuit configured to receive a continuous wave un-modulated radio frequency (RF) signal from a RFID interrogator, the RF signal conforming to a fast hop frequency hopping protocol in which each hop of a plurality of hops spans at least one bit but has then the totality of bits to be sent from a single RFID device data in a single commitment session;
- and
- a microcontroller linked to the transmit/receiving circuit.
